Data Story
About Lawn Care in Sheboygan County, Wisconsin
Lakeshore Conditions for Better Lawns
Sheboygan County scores a 60.9 for lawn difficulty, benefiting from a milder Zone 5b climate near Lake Michigan. While more manageable than the national average, it remains slightly more challenging than the statewide Wisconsin average of 64.4.
Milder Winters and Longer Seasons
The lake influence results in 2,315 growing degree days, offering a longer window for grass to establish than interior counties. Annual precipitation of 33.4 inches is consistent, though 6 extreme heat days require careful summer monitoring.
Higher Clay and Moderate Acidity
The soil contains 14.5% clay, which helps retain moisture and nutrients better than the sandy soils found elsewhere in the state. However, the pH of 5.77 is still below the ideal range, suggesting a need for periodic soil testing and amendments.
Addressing Recent Dry Spells
Nearly 70% of the county is currently abnormally dry after 24 weeks of drought conditions over the past year. Maintaining a higher mowing height of 3.5 inches can help shade the soil and reduce water evaporation during these periods.
Coastal Growing Windows
Perennial Ryegrass and Bluegrass blends thrive here, especially with the extended season that typically lasts until October 16. The best time for spring seeding is after May 3, when the threat of frost typically subsides.
